"Just in case anyone who's watching throughout the country, yes they're both available,"Brown said of daughters Ayla, 21, and Arianna, 19.

"And just in case anyone who's watching throughout the country they're both available. No, no. No. Only kidding, only kidding. Only kidding, only kidding. Arianna... Arianna's, definitely not available. But Ayla is. This is Arianna. This is Ayla. I can see I'm going to get in trouble when I get home."

Senator Scott Browns daughters Ayla and Arianna Brown,and at least one is available, as the Senator has stated.

And both of his daughters have been around and are "world-aware" too, from what I can see...

There's not as much about Arianna Brown, but I did find something here... [the language is a bit stilted in the article, but looks like it's a foreign source]

Arianna Brown January 20, 2010 by shezab

Arianna Brown is the younger of the two daughters Scott Brown has fathered in his wedlock with his spouse Gail Huff. Arianna Brown is a passionate girl in to her last teenage year. The charming faced nineteen years old Arianna Brown is preoccupied with the course of her first year studies at the renowned Syracuse University. The elder of the two daughters, twenty one years old Ayla Brown, is busy with final year of studies at Boston College.

Despite their academic fixates both Ayla and Arianna Brown were active members in their fathers campaign for the Senate seat during the Mass Elections. The two fair ladies were also very aggressive in countering any propaganda initiated by the opposing Martha Coakley and defended their father loud and clear when it came to sensitive issues such as abortion. Be wary of the fact that the late Senator, Edward Kennedy, was all for abortion rights and acts. Thus it was a hint his successors would need to take lead from.

Arianna Brown said that her father, Scott Brown, was not only good at handling the responsibilities of a dad but also that of a bread winner and hubby. She specifically stated that the seasoned politician was always concerned and updated with issues pertaining to the 3 women in his life and, as a consequence, would not be wary of his duties towards the other female citizens of the United States of America.

Scott Brown must surely be a proud father to have daughters like Arianna Brown and her elder sister.
